Airports And Covid: Assessing The Risks And Dangers

Airports are risky places for COVID transmission due to the large number of people passing through, often from different countries, and the challenge of maintaining physical distancing in crowded terminals. The risk of infection increases with exposure to the virus and the length of time spent in close proximity to an infected person. While aircraft cabin air is carefully controlled and filtered, the same cannot be said for airport terminals, which are large and complex, making regular cleaning and sanitization difficult. To minimize the risk of infection, it is recommended to maintain physical distance, wear masks, and practice good hand hygiene.

Maintaining physical distance in crowded airports

Airports can be crowded and overwhelming, and it can be challenging to maintain physical distance. Here are some tips to help you maintain physical distance in crowded airports:

• Be prepared and informed: Knowing the airport security procedures beforehand will help you navigate the airport with ease. Understand the screening processes, technology used, and regulations to comply with. This will make your experience less daunting and give you peace of mind.
• Dress simply: Wear clothes without heavy metal accessories, as they can trigger security alerts and slow down the screening process. Opt for a simple style that is comfortable and easy to move in.
• Have your documents ready: Ensure your travel documents, such as passports, visas, and tickets, are valid and easily accessible. This will save you time and reduce contact with others.
• Check-in online: Whenever possible, check-in online to avoid waiting in long queues at the airport. This will help you maintain distance and expedite your airport experience.
• Follow baggage policies: Familiarize yourself with your airline's baggage policy to avoid last-minute delays or fees. If possible, limit your luggage to carry-on bags only.
• Comply with liquid restrictions: Restrict liquids, gels, and aerosols to travel-sized containers (3.4 ounces or 100 ml) and place them in a clear, quart-sized bag for easy inspection.
• Keep electronics and toiletries accessible: Pack these items in an easily accessible part of your carry-on bag to facilitate screening and reduce the need for extensive bag searches.
• Enroll in expedited security programs: Consider signing up for programs like TSA PreCheck, which offer less intrusive screening and allow you to keep your shoes, laptops, and compliant liquids in your carry-on, streamlining the security process.
• Follow instructions: Always follow the instructions of security officers, as they are there to ensure your safety. Stay calm and comply with additional screening procedures if selected.
• Be mindful of your surroundings: Keep a safe distance from others whenever possible and avoid crowded areas. Stay vigilant and report any suspicious activities to airport security.
• Protect your belongings: Keep your belongings with you at all times. Do not leave them unattended, as this poses a security risk and makes them vulnerable to theft.
• Avoid sharing travel plans: Refrain from sharing personal travel details with strangers or over the phone where others can overhear. Be cautious when using public charging stations and Wi-Fi networks to protect your data.
• Stay up-to-date: Maintain awareness of your flight status and gate changes to avoid last-minute rushes and minimize stress.

The risk of being seated close to an infected person

Airports are crowded places, and with the current state of the world, it is not uncommon to find yourself seated close to an infected person during your flight. While the risk of contracting COVID-19 or any other infectious disease may vary depending on several factors, it is important to be aware of the potential dangers and take the necessary precautions.

Firstly, it is essential to understand that being in close proximity to an infected person increases your risk of exposure to the virus or bacteria they are carrying. The close quarters of an airplane make it easier for respiratory droplets containing the virus to spread from one person to another. Additionally, the recirculated air in the plane's ventilation system can contribute to the spread of airborne diseases.

Secondly, the duration of exposure also plays a significant role in the risk of infection. If you are seated near an infected person for an extended period, your risk of contracting the illness increases. This is especially true if the infected individual is coughing, sneezing, or exhibiting other symptoms that can spread the disease through respiratory droplets.

Thirdly, the type of infection and the stage of the disease in the infected person can impact the risk level. For example, during the peak of flu season, the chances of being exposed to the influenza virus are higher. Additionally, if the infected person is in the early stages of their illness, they are more likely to be contagious and pose a greater risk to those around them.

To minimise the risk of infection when seated close to an infected person, there are several precautions you can take. Firstly, wear a well-fitting mask that covers your nose and mouth. This will help to reduce the spread of respiratory droplets and lower your risk of inhaling the virus. Ensure you carry extra masks with you and change them regularly, especially if they become damp or soiled.

Secondly, practice good hand hygiene by using hand sanitiser frequently and avoiding touching your face. If possible, avoid direct contact with the infected person, and do not share personal items. Additionally, try to maintain a safe distance from the infected individual as much as possible, even if you are seated close by.

Lastly, if you notice someone seated near you exhibiting symptoms of an infectious disease, it is important to notify a flight attendant. They can assist in assessing the situation and may be able to relocate you to a different seat or provide additional support. Remember, your health and safety are important, and it is always better to be cautious when it comes to potential health risks.

The importance of regular hand sanitisation

Airports are busy places with large crowds and constant human traffic, which makes them risky for the spread of COVID-19. The importance of regular hand sanitisation in such environments cannot be overstated.

Firstly, it is important to understand that the novel coronavirus can be transmitted through respiratory droplets and by touching contaminated surfaces. When an infected person coughs, sneezes, or even talks, they release droplets that can contain the virus. These droplets can then land on surfaces, such as door handles, handrails, and counters, which other people may touch and inadvertently transfer the virus to their mouth, nose, or eyes. Therefore, regular hand sanitisation is crucial to break this chain of transmission.

Secondly, maintaining physical distance in crowded airport terminals can be challenging. The World Health Organization (WHO) recommends keeping at least a one-metre distance between individuals, but this may not always be possible in busy airports. Regular hand sanitisation helps reduce the risk of transmission when physical distancing cannot be maintained.

Thirdly, while most airlines pledge to clean seats and surfaces between flights, taking personal responsibility for your hygiene is essential. Using disinfectant wipes to clean armrests, screens, and other surfaces you come into contact with can further reduce your risk of infection. However, this should be complemented by regular hand sanitisation, as it is easy to touch your eyes, nose, or mouth without realising it.

Lastly, the risk of COVID-19 transmission is not limited to the airport itself but also includes the journey to and from the airport. Touching contaminated surfaces, such as public transport handrails or taxi door handles, can increase your risk of infection. Therefore, regular hand sanitisation is crucial, especially before and after touching surfaces in these environments.

In conclusion, regular hand sanitisation is a simple yet effective way to reduce the risk of COVID-19 transmission in airports and during travel in general. By sanitising your hands frequently, you not only protect yourself but also contribute to the overall safety of those around you. This small act can make a significant difference in preventing the spread of the virus and keeping everyone healthy.

The safety of recycled air in plane cabins

It is a common misconception that the air in an aircraft cabin is sealed and recycled endlessly. In reality, the air inside the cabin is continuously renewed and replaced with fresh air from outside the plane. This process involves sucking out the air from the cabin, mixing it with fresh air on a 50:50 basis, and then redelivering it to the cabin. This ensures that the cabin air is completely replaced around 15 to 30 times every hour, creating a clean and safe environment for passengers.

The air inside the cabin is filtered through high-efficiency particulate (HEPA) filters, which are the same devices used in hospital operating theatres. These filters are highly effective at removing bacteria, viruses, and other contaminants, with an efficiency rate of up to 99.995%. This makes the aircraft cabin air as clean as that of an operating theatre.

The airflow within the cabin is designed to flow in a top-to-bottom pattern, creating a curtain of airflow. This means that the air is not mixed between rows, reducing the risk of transmitting illnesses or infections. The excess cabin air is vented through valves at the rear of the plane to maintain constant cabin pressure.

While it is true that the arid air at high altitudes can lead to dryness and increased susceptibility to infection, modern long-haul planes like the Airbus A350 and 787 Dreamliner have addressed this issue by maintaining higher humidity levels. Staying hydrated, using eye drops and nasal spray, and moisturising can also help mitigate the effects of low humidity.

Overall, the recycled air in plane cabins is carefully managed and filtered to ensure the safety and well-being of passengers. The continuous renewal of air, combined with advanced filtration systems, makes it highly unlikely for illnesses to be transmitted through the air during a flight.

The impact of international travel on virus transmission

International travel has a significant impact on the transmission of viruses, including COVID-19. The movement of people across borders increases the risk of spreading infectious diseases, especially when travelling from areas with high transmission rates to regions with lower disease prevalence.

Airports, as hubs of international travel, play a crucial role in this dynamic. They are often crowded spaces with large numbers of people in close proximity, increasing the chances of viral exposure. While airport authorities are advised to implement regular cleaning and sanitization protocols, the complex infrastructure of these facilities can make it challenging to ensure comprehensive disinfection.

The risk of infection is heightened on airplanes, where physical distancing is difficult to maintain. Even with middle seats kept vacant, passengers may still be within the risk zone of an infected individual, as defined by the World Health Organization (WHO). The duration of the flight also influences the likelihood of infection, with longer flights posing a higher risk.

Additionally, the air circulation systems within plane cabins have been a subject of concern. While the WHO asserts that research shows a low risk of communicable disease transmission onboard aircraft due to their ventilation and filtration systems, there is evidence that the new coronavirus has spread in other air-conditioned environments.

To mitigate these risks, public health authorities recommend various preventive measures. These include maintaining physical distance, wearing masks, practising proper hand hygiene, and avoiding face-touching. However, it is important to recognize that these measures only manage the risk and cannot eliminate it entirely. The most effective way to avoid contracting COVID-19 may be to refrain from travelling and stay at home.
